flashchips: Add write-protect support for MXIC MX25U25643G

The MX25U25643G has a WPSEL bit in the security register, but the MX25U25635F does not.
Therefore, take them apart.

We have tested --wp-enable, --wp-disable, --wp-list and --wp-range
commands for write-protect feature.

The MX25U25643G has been tested by ch341a programmer : read, write,
erase and wp.

MX25U25643G datasheet is available at the following URL:
